I'm currently having to store my car outside, with no chance of putting a lean-to over it as it's a semi communal space. It's been fine over the last few months as sun has dried out any moisture from the small leaks, but this week with the extended rain and cold it's completely sodden inside. I have removed the carpets so the water drains out the drain holes but a roof cover would be useful to keep it a bit drier. Ideally I don't want to spend too much, so likely rules a custom one out, so has anyone had any success with off the shelf covers? MX5? MR2?

Ideally I just want one to cover the roof/cockpit area as have access to one that covers the whole car, but it barely fits in the front boot when folded!

I haven't ruled making one myself out - anyone done this and if so what material did you use?

Elise shower cap?
